Beit known that I,`l`noni.r. s'MCtIULLoUon, a citizen ot the United States, residing at Kansas City, in the county oi Jackson and Stat-e oi Missouri, have invented certain new and useful liiiprovements in. Artii'icial Teeth; and I do declare tlh `'ollowing to be a ifull,

such as will enable others skilled in the art to which it appei'tains to make and use the same, reference being had to vthe accompanying drawings, and to the figures of reference marked thereon, which form a part' of this specification. 1 A

My invention relates to improvements in artiticial teeth and has 'for its principal object to provide a device ot' that class which may be firmly and peimanently mounted in an ordinary bridge, plate,`or like carrier.

A further object of' my invention is to provide the im iroved details of' structure which will present y be fully described and pointed out in the claims, reference being had to the accompanying drawings forming part ol' this s ecification, in which like reference numera s refer to like parts throughout the several views, and in which z- Figure I is a front view of an artificial tooth constructed according to my invention. Fig. Il is a view of saine in side elevation. Fig. HI isa central longitudinal scction'of saine. Fig. IV is a cross section on the line lV-JV, Fig. Il. Fig. Y is a similar View with the cup socket removed. Fig. is a view showing the manner of combining the teeth with a plate, or like structure.

Referring more in detail to the parts z-l designates wplate, of the usual construction and material, and adapt-ed for carrying va set of artificial teeth. Yifithin plate 1 are rccesses, of various shapes and sizes, and scoured in each of said recesses is a socket 2, preferably ol' platinum or like material, which is cut away in front to expose that portion oi' a porcelain or like tooth body which it may carry, but is provided with i'ull back an'd base portions and a front rim 4, within which said porcelain or like body may be posited and firmly secured, preierably by cement. At cach side and opening thri'iugh the root eud 'it body 3, is a groove .5, which extends almost. to'tlie free end oi' the tooth body and there provided with a shoulder i3; the sido ol' such shoulder, :is well as the groove sides, beingl prclcrably squared and the tooth body portion being' Specification o/Letters Patent.

'ided with au innershould'er or ledge 3 t'. rin base 2 may abut. Projecting inwardly from the side of sockets 2 are the ribs 7, .i'hicli 'are adapted to fit within the grooves 6 when the teeth are posited vin their sockets, as will be When in use, the sockets which may be made up at a factory, or a dentists private laboratory, are applied to a mount-ing of any, suitable description, such as a bridge or plate, that is adaptable for carrying one or morev artificial teeth, as may be desired. Vhen, for instance, it is desired to insert a inist vwhich the socket cup single artificial tooth between natural teeth in a patientsmouth, the socket is fitted to the recess and permanently fixed in position by any ot' the well known devices used for' that purpose; the porcelain or like tooth body member isthen fitted to the space between the natural teeth and adjusted to the socket, the groove and rib arrangement permitting the porcelain or like body to be accurately guided to the position which it will ultimately occupy, although permitting its free insertion into and withdrawal from the socket while being so adjusted. When the porcelain or like body has been properly fitted, cement is laced in the socket and the. tooth body inally inserted and permanently held therein, as in the use of an ordinary crown, the groove and rib parts meshing together and forming a union that will prevent the tooth body loosening in its socket when in use.

The application ot' my improvements to plate work is substantially similar to that of' the single mounting, with the exception that in the former a number of sockets are set side by side in the plate and the artificial teeth fitted to form a set.

ln the larger use 'the sockets may be soldered to a suitable portion of the plate, or

may be baked or formed into the plate body,4

the application of the porcelain or like body to the socket being as previously described.

Having thus described my invention, what- I claim as new therein and desire to secure by Letters Patent is:

.1. An artificial tooth compi-isiliU a body member, and a socket cup adapted tor inclosing said member at the base, rear and sides and exposing same at the front and free cud, and a rim on said base adapted for project ion overa portion of the exposed front of said body member, said body member being provided with side grooves' and said cup with ribs adapted 'for seatin in said grooves when hletgarts are' assemble substantially as set o s 2. An articial tooth com rising a porce- 5 lain body member having si e grooves opening through its root end and a transverse eripheral shoulder for abutment against the ree end of a socket cup, substantially as set g forth. g Lo 3. An artiiciai tooth comprising a porce- -Lain boiyu'member ada. ted for insertion into' *la socketI cup, said bo y member being provided'with grooves adapted for coperation with inturned ribs on a socket cup and with a ledge 'on its outer surface' for abutment 15 against the end of a socket cup, substantially as set forth. y*

In testimony-whereof I affix my signature in presence of two witnesses.
